BACKGROUND

Field

Various embodiments disclosed herein relate to doorbells. Certain embodiments relate to doorbell systems that detect packages.

Description of Related Art

Doorbells can enable a person located outside of an entry point, such as a door, to alert a person inside of an entry point that someone outside would like to talk to someone inside. Doorbells sometimes include a button located near a door, such as a front door, side door, or back door of a home, office, dwelling, warehouse, building, or structure. Doorbells are sometimes used near a gate or some other entrance to a partially enclosed area. Pushing the doorbell sometimes causes a chime or other alerting sound to be emitted.

A doorbell chime can be communicatively coupled with a doorbell while the chime is located remotely relative to the doorbell. For example, the doorbell can be coupled to an exterior surface of a building (e.g., near an entryway) and the chime can be coupled to an interior surface of a building.

Delivery parcels (e.g., packages, envelopes) are often left in a publicly accessible entryway of a building. These delivery parcels are sometimes stolen before the rightful owner can pick up the delivery parcels. Thus, there is a need for systems that reduce the likelihood of delivery parcel theft.

System Embodiments

Communication systems can provide a secure and convenient way for a remotely located individual to communicate with a person who is approaching a sensor, such as a proximity sensor or motion sensor, or with a person who rings a doorbell, which can be located in a doorway, near an entrance, or within 15 feet of a door. Some communication systems allow an individual to hear, see, and talk with visitors who approach at least a portion of the communication system and/or press a button, such as a doorbell's button. For example, communication systems can use a computing device to enable a remotely located person to see, hear, and/or talk with visitors. Computing devices can include computers, laptops, tablets, mobile devices, smartphones, cellular phones, and wireless devices (e.g., cars with wireless communication). Example computing devices include the iPhone, iPad, iMac, MacBook Air, and MacBook Pro made by Apple Inc. Communication between a remotely located person and a visitor can occur via the Internet, cellular networks, telecommunication networks, and wireless networks.

Referring now to FIG. 1, the doorbell 202 can record video and audio, which can then be sent to a remote computing device 204. The remote computing device 204 displays the video and emits the audio from the doorbell 202 to enable a user of the remote computing device 204 to see and hear a visitor. For example, when the doorbell 202 detects a visitor (e.g., a motion sensor 218 detects a visitor or the visitor presses the button 212), the doorbell 202 can send a push notification to the remote computing device 204. A user of the remote computing device 204 can then see and hear the visitor.

The user of the remote computing device 204 can select a button on application software running on the remote computing device 204 to initiate two-way audio and/or video communication with the visitor. In some embodiments, the user can see and hear the visitor, and the visitor can hear (but not see the user). In several embodiments, the user can hear (but not see) the visitor. In some embodiments, the user and visitor can both see and hear each other (e.g., the doorbell 202 can include a display screen to show live video captured by a camera of the remote computing device 204).

Doorbell systems can be a portion of a smart home hub. In some embodiments, the doorbell system 200 forms the core of the smart home hub.

Selecting the button 276 when the system is attempting to establish two-way communication between the visitor and the user can start two-way communication. The button 276 can include the words “End Call” during two-way communication between the visitor and the user. Selecting the button 276 during two-way communication between the visitor and the user can terminate two-way communication. In some embodiments, terminating two-way communication still enables the user to see and hear the visitor. In some embodiments, terminating two-way communication causes the computing device 204 to stop showing video from the doorbell and to stop emitting sounds recorded by the doorbell.

In some embodiments, the user interface 240 opens as soon as the doorbell detects a visitor (e.g., senses indications of a visitor). Once the user interface 240 opens, the user can see and/or hear the visitor even before “answering” or otherwise accepting two-way communication, in several embodiments.

Some method embodiments include detecting a visitor with a doorbell. The methods can include causing the user interface to display on a remote computing device 204 due to the detection of the visitor (e.g., with or without user interaction). The methods can include displaying video from the doorbell and/or audio from the doorbell before the user accepts two-way communication with the visitor. The methods can include displaying video from the doorbell and/or audio from the doorbell before the user accepts the visitor's communication request. The methods can include the computing device simultaneously asking the user if the user wants to accept (e.g., answer) the communication request and displaying audio and/or video of the visitor. For example, in some embodiments, the user can see and hear the visitor via the doorbell before opening a means of two-way communication with the visitor.

In some embodiments, the software includes means to start the video feed on demand. For example, a user of the computing device might wonder what is happening near the doorbell 202. The user can open the software application on the computing device 204 and instruct the application to show live video and/or audio from the security device 202 even if no event near the doorbell 202 has triggered the communication.

In several embodiments, the security device 202 can be configured to record when the security device 202 detects movement and/or the presence of a person. The user of the computing device 204 can later review all video and/or audio records from when the security device 202 detected movement and/or the presence of a person.

Referring now to FIG. 1, in some embodiments, the server 206 controls communication between the computing device 204 and the doorbell 202, which can be a doorbell with a camera, a microphone, and a speaker. In several embodiments, the server 206 does not control communication between the computing device 204 and the doorbell 202.

In some embodiments, data captured by the doorbell and/or the computing device 204 (such as videos, pictures, and audio) is stored by another remote device such as the server 206. Cloud storage, enterprise storage, and/or networked enterprise storage can be used to store video, pictures, and/or audio from the doorbell system 200 or from any part of the doorbell system 200. The user can download and/or stream stored data and/or storage video, pictures, and/or audio. For example, a user can record visitors for a year and then later can review conversations with visitors from the last year. In some embodiments, remote storage, the server 206, the computing device 204, and/or the doorbell 202 can store information and statistics regarding visitors and usage.

FIG. 3 illustrates an embodiment in which a doorbell 202 is connected to a building 300, which can include an entryway 310 that has a door 254. A visitor 388 can approach the doorbell 202 and then can be detected by the doorbell 202. The visitor 388 can press the doorbell button 212. The user of the doorbell 202 can configure the doorbell 202 such that when the visitor 388 presses the doorbell button 212, the user receives a notification regarding the visitor 388.

Electrical wires 304 can electrically couple the doorbell 202 to the electrical system 312 of the building 300, such that the doorbell 202 can receive electrical power from the building 300. The building can include a door lock 250 to lock the door 254.

A wireless network 308 can allow devices to wirelessly access the Internet. The doorbell 202 can access the Internet via the wireless network 308. The wireless network 308 can transmit data from the doorbell 202 to the Internet, which can transmit the data to remotely located computing devices 204. The Internet and wireless networks can transmit data from remotely located computing devices 204 to the doorbell 202. In some embodiments, a doorbell 202 connects to a home's WiFi.

As illustrated in FIG. 3, multiple computing devices 204 can communicate with one doorbell 202. In some embodiments, one computing device 204 (e.g., a laptop, a smartphone, a mobile computing device, a television) can communicate with multiple doorbells 202.

In some embodiments, the doorbell 202 can communicate (e.g., wirelessly 230) with a television 306, which can be a smart television. Users can view the television 306 to see a visitor and/or talk with the visitor.

FIG. 4 illustrates an internal view of the doorbell 202. Doorbells 202 can include a chip 480 (e.g., integrated circuits, microprocessor, computer) and a memory 492. Doorbells 202 can also include a microphone 484 and a speaker 488. The speaker 488 can comprise a flat speaker and a sound chamber 460 configured to amplify an emitted sound. The flat speaker can be located in the sound chamber. Some doorbell embodiments include a proximity sensor 500. In several embodiments, doorbells 202 include a wireless communication module 504, such as a WiFi module. The communication module 504 can have an integrated antenna. In some embodiments, an antenna is contained within the outer housing 224.

The doorbell 202 can include one or more heating elements 508 configured to regulate the temperature of the doorbell 202. For example, doorbells 202 can be used in very cold environments, such as in Alaska. The heating element 508 can be used in various methods to protect temperature sensitive portions of the doorbell 202 from cold weather.

While protecting the doorbell 202 from cold weather can be important in some embodiments, protecting visitors from excessive heat can also be important in some embodiments. Excessive heat could burn visitors as they “ring” the doorbell (e.g., press the doorbell button 212 shown in FIG. 1). The doorbell 202 can include a thermometer 512 to enable the system to determine the temperature inside a portion of the doorbell 202 and/or outside the doorbell 202.

Several embodiments can be configured for 9 to 40 volts alternating current (“VAC”) and/or 9 to 40 volts direct current (“VDC”). Some embodiments convert input electricity into direct current (“DC”), such as 12 VDC. Several embodiments include a converter 494 for power conversion (e.g., converting electrical energy from one form to another). The converter 494 can convert input power (e.g., from wiring in a building) to a suitable power form for the doorbell 202. The power conversion can convert between AC and DC, change the voltage, and/or change the frequency. The converter 494 can include a transformer and/or a voltage regulator. In several embodiments, the converter 494 can include a voltage stabilizer, a linear regulator, a surge protector, a rectifier, a power supply unit, a switch, an inverter, and/or a voltage converter. In some embodiments, the converter 494 converts 50 Hertz (“Hz”) power into 60 Hz power.

The electrical components of the doorbell 202 (e.g., the camera assembly 208, the memory 492, the chip 480, the speaker 488, the converter 494, the microphone 484, the lights 458, a rectifier, the proximity sensor 500, the communication module 504, the heating element 508, the electrical connectors 510, the thermometer 512, the image analysis system 520, and the battery 462) can be electrically coupled to a printed circuit board (“PCB”) 516 and can receive electrical power from the PCB 516.

The PCB 516 and the electrical components of the doorbell 202 can be the electrical system 456 of the doorbell 202. Additional details regarding the PCB 516 and the electrical components of the doorbell 202 are described in U.S. Nonprovisional patent application Ser. No. 14/612,376; filed Feb. 3, 2015; and entitled DOORBELL COMMUNICATION SYSTEMS AND METHODS. The entire contents of patent application Ser. No. 14/612,376 are incorporated by reference herein.

The doorbell 202 can include a detection system 528. The doorbell 202 may be configured to alert the user to the presence of a visitor 388 by, for example, sounding a chime 302.

Although some embodiments are described in the context of devices and systems, the device embodiments and the system embodiments can also be formulated as methods. Devices and systems described herein can be applied to the methods incorporated by references herein.

Although some embodiments are described in the context of methods, the method embodiments can also be formulated as devices and systems. Methods described herein can be applied to the devices and systems incorporated by references herein.

Doorbell Package Detection Embodiments

Millions of parcels are delivered each week. Often, these parcels are delivered during working hours when the homeowner is away at work. When the parcels are too large to fit in a mailbox, mail carriers and other delivery personnel often leave the parcels on a front porch of the home or even in a common area of an apartment building.

These parcels can sit unattended for long periods of time. Thieves see unattended parcels as soft targets and often drive around neighborhoods looking for unattended parcels. Thieves can jump out of a car, steal the parcel, and then drive away within seconds. With shopping being done increasingly online and the resulting increase in parcel deliveries, parcel theft is becoming more and more of a problem. Until now, little has been done to combat parcel theft.

Embodiments described herein include high-tech floor coverings (e.g., mats) that can communicate wirelessly with a smart doorbell. The floor coverings can include sensors, such as pressure sensors and optical sensors, to detect when a parcel (e.g., a package, an envelope) is placed on the floor covering.

The floor covering can “wake up” the smart doorbell by sending a wireless communication (e.g., via Bluetooth Low Energy) to the doorbell. The doorbell can then send an alert to a remote computing device (e.g., a smartphone) to alert the user regarding the arrival or removal of the delivery parcel.

If the doorbell's motion sensor and/or camera detects a visitor when a delivery parcel is located on the floor covering, the doorbell can start recording a video. If the visitor takes the delivery parcel, then the video will document who took the delivery parcel. If the system senses that the visitor removed the delivery parcel from the floor covering, the system can send an alert (e.g., a push notification) to the remote computing device. This alert can include the video.

The system can recognize when a delivery parcel has arrived via image recognition. The system can create a security zone around the delivery parcel. If a visitor enters the security zone, the system can send an alert to the remote computing device and/or emit lights and sounds (e.g., from the doorbell, from the floor covering). This security zone can be a portion of the field of the view of the camera.

FIG. 5 illustrates a diagrammatic view of a delivery parcel detection system 200. A doorbell 202 is mounted to an exterior of a building 300 (e.g., in an entryway 310 near a door 254). The doorbell 202 can include a camera assembly 208 and a motion detector 218. The camera assembly 208 and the motion detector 218 can detect when a visitor 388 approaches the doorbell 202. This configuration enables the doorbell 202 to monitor the delivery parcel 241, which can be located in the entryway 310.

The floor covering 235 can communicate with the doorbell 202 (e.g., can send information to the doorbell 202). In some embodiments, the floor covering 235 is communicatively coupled (e.g., wirelessly coupled) to a wireless network 308 (e.g., of the building 300). The doorbell 202 can be communicatively coupled to the same wireless network 308 as the floor covering 235.

In several embodiments, the floor covering 235 communicates directly (via wires or wirelessly) with the doorbell 202. For example, Bluetooth, Bluetooth Low Energy, radio waves, and/or any suitable short-range communication system or protocol can be used by the communication system 504 b of the floor covering 235 to enable the floor covering 235 to communicate with the doorbell 202.

The doorbell 202 can communicate with a remote computing device 204, which can be located inside the building 300, outside the building 300, or even many miles away from the building 300. The doorbell 202 can be communicatively coupled with the remote computing device 204 via the wireless network 308, the Internet, cellular networks, telecommunication networks, the server 206, and/or any other suitable system.

The delivery parcel 241 is located on top of a floor covering 235, which can be a mat. As used herein, the term “delivery parcel” is used broadly and can mean a box or envelope that is usually given, sent, or delivered to a person. For example, a mail carrier, a FedEx Corporation delivery worker, and any suitable delivery service can place a delivery parcel 241 near the building 300. In some cases, a friend or neighbor places a delivery parcel 241 near the building 300 (e.g., on the floor covering 235). Delivery parcels 241 can be large boxes, small boxes, odd-shaped packages, large envelopes, small envelopes, and/or any object that is placed on the floor covering 235.

As used herein, the term “floor covering” is used broadly. Floor coverings are configured for placing on the ground. Floor coverings can be mats. Mats can have a length and width that are more than ten times their thickness, which is measured vertically upward when the mat is placed on the ground. In some embodiments, mats can be used to wiping soiled shoe soles; however, not all mats are used for wiping shoe soles. For example, mats can be specially designed such that a delivery person can place parcels on the mats. Mats can be made of fabric or can be molded from plastic.

In FIG. 5, the floor covering 235 is located directly in front of the door 254, but in several embodiments, the floor covering 235 is located on the ground to the side of the door 254 to discourage visitors 388 from stepping on the floor covering 235.

The floor covering 235 can include sensors 239 to detect whether a delivery parcel 241 is located on the floor covering 235. In some embodiments, these sensors 239 are pressure sensors.

The pressure sensors can be thin and flexible. Tekscan, Inc., having an office in South Boston, Mass., makes high resolution pressure sensors that can be embedded in floor coverings 235. The nature of Tekscan's pressure sensors enables the system 200 to detect the footprint and the weight of the delivery parcel 241. This information can be compared to a database of parcels that are expected to be delivered to the address at which the floor covering 235 is located. This comparison enables the system 200 to determine which expected parcel has a footprint and/or weight indicative of being the parcel 239 located on the floor covering 235. The communication 230 b to the remote computing device 204 can then include information regarding the contents of the parcel 241.

Digi-Key Corporation, having an office in Thief River Falls, Minn., sells many types of pressure sensors that can be embedded into the floor covering 235. Digi-Key sells pressure sensors from Freescale Semiconductor, Inc. that can be mounted to a PCB of the floor covering 235. Digi-Key also sells pressure sensors from STMicroelectronics N.V. that can be surface mounted on the floor covering 235.

In several embodiments, floor covering 235 comprises sensors 239 that are optical sensors. For example, the optical sensors can include light emitting diodes (“LEDs”) that emit light upwards (away from the ground). The optical sensors can also include light sensors configured to detect the light from the LEDs. The optical sensors can face upwards. If no object is located on top of the floor covering 235, the light from the LEDs simply continues upward and is not sensed by the light sensors. If an object is located on top of the floor covering 235, the light from the LEDs can reflect off the object such that the light is redirected back towards the light sensors. As a result, the light sensors can detect the object (e.g., a delivery parcel).

A light sensor can be located in the same upward facing hole as an LED, such that the light sensor is configured to detect light emitted from the LED if a delivery parcel covers the hole to deflect the light emitted from the LED towards the light sensor. The light sensor can be configured to only detect a specific type of light emitted by the LED, such that the sensor system does not confuse the presence or lack of sunlight as the presence or removal of a delivery parcel.

As shown in FIG. 5, a delivery parcel detection system 200 can include a doorbell 202 having a first wireless communication system 504 (shown in FIG. 4); and a floor covering 235 configured for placement on the ground (e.g., an entryway floor). The floor covering 235 can comprise a sensor 239 configured to detect a first indication of a delivery parcel 124 on the floor covering 235. The floor covering 235 is communicatively coupled to the doorbell 202 (e.g., via wires or wirelessly). The doorbell 202 can be mounted to a wall of the building 300 while the floor covering is located on the ground. The floor covering 235 can be a mat that includes a battery to provide electrical power to electrical components of the floor covering 235.

The system 200 can include a first communication 230 a (e.g., a Bluetooth wireless communication) sent from the floor covering 235 to the doorbell 202 in response to the floor covering 235 detecting the first indication of the delivery parcel 241. The system 200 can also include a second communication 230 b (e.g., a wireless communication) sent from the doorbell 202 to a remote computing device 204 in response to the doorbell 202 receiving the first communication 230 a.

The doorbell 202 can include a camera 208. The second communication 230 b can comprise a first picture 243 taken by the doorbell 202, such that the doorbell 202 is configured to send the first picture 243 to the remote computing device 204 in response to the floor covering 235 detecting the first indication of the delivery parcel 241. As illustrated in FIG. 5, the first picture 243 can show the delivery parcel 241 to enable the user of the remote computing device 204 to see the delivery parcel 241. The first picture 243 can be sent directly from the doorbell 202 to the computing device 204, but in many embodiments, the first picture 243 is sent from the doorbell 202 to the remote computing device 204 indirectly (e.g., via a server 206).

The first indication of the delivery parcel 241 can be a weight of the delivery parcel 241 sensed by the floor covering 235 (e.g., via a pressure sensor). The first indication of the delivery parcel 241 can also be a light sensed by a light sensor (e.g., as described above). The first indication can be due to the arrival of the delivery parcel (e.g., a pressure increase, a light increase) or can be due to a removal of the delivery parcel from the floor covering 235 (e.g., a pressure decrease, a light decrease).

The first indication can be associated with an arrival of the delivery parcel 241 to the floor covering 235. The first indication can be associated with a removal of the delivery parcel 241 from the floor covering 235. The communication 230 b sent to the remote computing device 204 can indicate if the delivery parcel 241 arrived or was removed.

The system 200 can also comprise a first alert 232 regarding the delivery parcel 241. In some embodiments, the first alert is a push notification sent to the remote computing device 204 (e.g., sent wirelessly over various communication networks, sent via WiFi). The first alert 232 can be a text message on the remote computing device. The first alert 232 can be a graphic displayed on the screen of the remote computing device 204. The graphic can be configured to enable a user of the remote computing device 204 to see information regarding the delivery parcel (e.g., a picture of the parcel, a time of parcel arrival, a time of parcel removal, an identity of the person who delivered the parcel, an identity of the person who removed the parcel).

The first alert 232 can be displayed on the remote computing device 204 in response to the remote computing device 204 receiving the second communication 230 b from the doorbell 202. The system 200 can include a graphical user interface 240 displayed on the remote computing device 204. The graphical user interface 240 can be configured to display information regarding the delivery parcel 241.

This information regarding the delivery parcel 241 can be displayed simultaneously with weather information (e.g., as detected by the system 200) described in U.S. Nonprovisional patent application Ser. No. 14/813,479; filed Jul. 30, 2015; and entitled DOORBELL COMMUNICATION SYSTEMS AND METHODS, which is incorporated by references herein. For example, the display can show information such as, “your package is outside in the rain” or “wind of 25 miles per hour is blowing your mail away.”

As shown in FIG. 5, the graphical user interface shows a picture 243 of the delivery parcel 241. The graphical user interface 240 can display the following information, and any other relevant information, regarding the delivery parcel 241: delivery time, to whom the delivery parcel is addressed, sender information, contents, and the status. The status can indicate whether the delivery parcel 241 is currently located on the floor covering 235. The status can also indicate if the delivery parcel 241 is still within a detection range (e.g., a field of view of the camera 208) of the doorbell 202.

The graphical user interface 240 is configured to enable changing at least one setting of the lights 216 b of the doorbell 202. The user interface 240 can include buttons 237 (e.g., touch screen icons, which are not necessarily physical buttons). At least one of these buttons 237 can be a light adjustment button configured to enable changing settings of a light 216 b (e.g., an LED) of the doorbell 202.

The setting that is changed by the button 237 can be a color of the light 216 b. For example, the color can change from red to green to blue to white. Millions of color combinations are possible with LEDs. The color can correspond with holiday colors or special occasions.

The setting that is changed by the button 237 can be a brightness of the light 216 b. For example, the button 237 can act as a light dimmer.

In some embodiments, the system 200 automatically changes the setting in response to the floor covering 235 detecting the first indication of the delivery parcel 241. For example, parcel 241 removal can cause a red light to flash from the doorbell 202 and/or from the floor covering 235. Parcel 241 arrival can cause a green light to flash.

In several embodiments, the system 200 (e.g., the doorbell) emits a sound or audible words in response to detecting the arrival or removal of the parcel 241. The sound and/or words can thank the deliver and/or warn the remover.

Many types of warning sounds can emitted from the doorbell 202 (e.g., from the speaker 488 shown in FIG. 4) in response to the system 200 detecting a removal of the delivery parcel 241 from the floor covering 235. The floor covering 235 can also emit the warning sound from a speaker 488 b. The warning sound can be a voice saying a predetermined message such as, “stop, package theft is against the law.” Reduced pressure, as sensed by the floor covering 235, can enable the system 200 to detect the removal of the parcel 241.

In addition to having a speaker 488 b, the floor covering 235 can also include many warning lights 216 c, which can be LEDs. In several embodiments, a warning light and a warning sound are emitted from at least one of the doorbell 202 and the floor covering 235 in response to the system 200 detecting motion (e.g., via the motion detector 218).

In some embodiments, a warning light and a warning sound are emitted from at least one of the doorbell 202 and the floor covering 235 in response to the system 200 detecting that an object (e.g., a visitor 388) has moved into a field of view of a camera 208 of the doorbell 202. For example, if a visitor 388 approaches the doorbell 202 and/or the floor covering 235 while a parcel 241 is located on the floor covering 235 and/or detected by the doorbell 202, the doorbell 202 and/or the floor covering 235 can emit the warning light from the lights 216 b, 216 c and can emit the warning sounds from the speakers 488 b, 488 (shown in FIG. 4). Thus, the system 200 can emit the warnings in response to motion and/or object detection plus in response to the system 200 determining the delivery parcel 241 is located on the floor covering 235.

In some embodiments, the system 200 is configured to not emit a warning if a person carrying the remote computing device 204 is the one removing the parcel 241. In contrast, if a person is removing the parcel 241 when the remote computing device 204 is located far from the doorbell 202 (e.g., is away from home), then the person removing the parcel 241 might be a thief. Thus, some embodiments include a warning light and a warning sound emitted from at least one of the doorbell 202 and the floor covering 235 in response to the system 200 detecting a removal of the delivery parcel 241 from the floor covering 235 during a period when the system has determined that the remote computing device 204 is at least one of not located within a predetermined distance of the doorbell 202 and not located within a detection range of the doorbell 202. The predetermined distance can be within 30 meters of the doorbell 202.

The system 200 can determine if the computing device 204 is within a predetermined distance based on Global Positioning System (“GPS”) information from the doorbell 202 and the remote computing device 204. The system 200 can determine if the remote computing device 204 is within a detection range of the doorbell 202 via the doorbell 202 trying to communicate with the remote computing device 204 directly via a short-range communication protocol such as Bluetooth. If the remote computing device 204 does not respond to the Bluetooth signal from the doorbell 202, then the system 200 determines that the remote computing device 204 is outside of the detection range of the doorbell 202.

Doorbell 202 power consumption minimization can be important, especially in embodiments in which the doorbell 202 is powered exclusively via battery power (rather than via electrical wires 304 from a building 300 as shown in FIG. 3). In some embodiments, the doorbell 202 is in a Sleep Mode that precludes the camera 208 from recording without exiting the Sleep Mode. The floor covering 235 detecting parcel 241 delivery, movement, or removal can cause the doorbell 202 to exit the sleep mode, take a picture, and/or start recording a video. The picture and video can be sent to the server 206 and/or to the remote computing device 204. In some embodiments, the doorbell 202 comprises an electrical power consumption rate that increases in response to the floor covering 235 detecting the first indication of the delivery parcel 241 (e.g., due to the activity of the camera 208).

In several embodiments, the doorbell 202 comprises a camera 208 configured to take at least one picture in response to the floor covering 235 detecting the first indication of the delivery parcel 241. The sensor 239 can comprise a pressure sensor configured such that placing the delivery parcel 241 on the floor covering 235 enables the pressure sensor to detect the first indication.

A camera 208 can be electrically coupled to the doorbell 202. The camera 208 can also be electrically coupled to the floor covering 235. The system 200 can comprise a video taken by the camera 208 in response to the system detecting a removal of the delivery parcel 241. A video can be taken by the camera 208 in response to the camera 208 detecting an object (e.g., a visitor 388) that has moved into a field of view of the camera 208 during a period when the system 200 has determined the delivery parcel 241 is located on the floor covering 235.

The doorbell 202 can include a motion detector 218. The floor covering can also include a motion detector 218, which can have all the same features and functions of the motion detector 218 of the doorbell 202. In some embodiments, a motion detector 218 and a camera 208 are electrically coupled to at least one of the doorbell 202 and the floor covering 235. The system 200 can comprise a video taken by the camera 208 in response to the motion detector 218 detecting a motion indication during a period when the system 200 has determined the delivery parcel 241 is located on the floor covering 235. A second communication 230 b can be sent from the doorbell 202 to the remote computing device 204 in response to the motion detector 218 detecting the motion indication. The second communication 230 b can comprise the video.

In several embodiments, the first indication is associated with a removal of the delivery parcel 241 from the floor covering 235. The system can further comprise a first communication 230 a sent from the floor covering 235 to the doorbell 202 in response to the floor covering 235 detecting the first indication. The system can also comprise a second communication 230 b sent from the doorbell 202 to a remote computing device 204 in response to the doorbell 202 receiving the first communication 230 a. As described previously, a camera 208 can be electrically coupled to at least one of the doorbell 202 and the floor covering 235. The second communication 230 b can comprise a picture taken by the camera 208 within five seconds of the sensor 239 detecting the first indication. Taking the picture within five seconds can help ensure the picture (which can be a video) shows the thief who removed the parcel 241 (via the system 200 taking the picture before the thief is able to run away).

The system 200 can take pictures 245 when the system 200 detects the arrival of the parcel 241, a visitor 388 moving (e.g., towards the doorbell 202), a movement of the parcel 241, and/or the removal of the parcel 241. The communication 230 b between the doorbell 202 and the remote computing device 204 can include these pictures 245. Thus, the system 200 can send many pictures to the remote computing device 204 depending on the preferences of the user of the remote computing device 204. As used herein, sending a video includes sending a picture (because a picture is a portion of a video). Thus, a picture can be a still picture and can be an instant of a video (e.g., can be one frame of a video).

A doorbell communication 230 d regarding the parcel 241 can be sent via a wireless network 308 (e.g., of the building 300), via Bluetooth, via cellular networks, via telecommunication networks, via the Internet, and/or via a server 206 to the remote computing device 204. In some embodiments, another remote computing device 204 n also receives the doorbell communication 230 d regarding the parcel 241. The doorbell communication 230 d can include a picture 243 of the parcel 241 and/or a picture 243 taken by a camera 208, 208 b of the system 200 at a time within 5 seconds of the doorbell 202 and/or the floor covering 235 detecting of an indication of the parcel 241 (e.g., an arrival of the parcel 241, a movement of the parcel 241, and/or a removal of the parcel 241 from the floor covering 235 and/or from a field of view of the doorbell 202).

In some embodiments, the second remote computing device 204 n is a neighbor's remote computing device. The doorbell communication 230 d can include a request for the neighbor to pick up and move the parcel 241. In response to this request, the neighbor can bring the parcel 241 to the neighbor's home to prevent the parcel 241 from being stolen until the parcel's owner can get the parcel 241 from the neighbor.

Some embodiments of the system 200 use the floor covering 235 to detect parcels 241. Some embodiments of the system 200, however, do not use the floor covering 235 to detect parcels 241. For example, the doorbell 202 can use the camera 208 to detect parcels 241.

The doorbell 202 can use the camera 208 to take a picture 243 when the doorbell 202 detects movement (via the camera 208 and/or via the motion detector 218). The system 200 can then analyze the picture 243 to determine if the picture 243 shows a parcel 241. This picture analysis can use image recognition procedures to look for indications of a parcel 241 in the picture 243. For example, the image recognition procedure can include looking for colors that are typical of cardboard delivery boxes (e.g., brown). The image recognition procedure can include looking for flat surfaces connected at approximately ninety degree angles (which are indicative of a box shape). The image recognition procedure can include looking for flat surfaces located in different locations in images taken at different times (which is indicative of a box being carried towards the doorbell 202 such that the box is located in a first position in a first picture and is located in a second position in a second picture taken within 10 seconds of the first picture).

The parcel 241 detection procedure can also include using the microphone 484 (shown in FIG. 4) of the doorbell 202 to listen for sounds indicative of delivery vehicles (e.g., the sounds of large engines and heavy trucks typical of delivery services such as FedEx Corporation and United Parcel Service, Inc.). The system 200 can also use the microphone 484 to listen for sounds indicative of a parcel 241 being dropped on a floor (e.g., of an entryway 310). The system 200 can then analyze the sounds to identify that the parcel 241 has been delivered to the building 300 (e.g., the parcel 241 is located outside of the building 300 within a detection range of the doorbell 202).

The system 200 might hear a delivery vehicle stop within a detection range of the doorbell 202 (e.g., within a range that the microphone 484 can hear the delivery vehicle). However, the system 200 might not know if the delivery vehicle left a parcel 241 at the building 300 or at a neighbor's home. The system 200 can distinguish between deliveries to neighbors' homes and deliveries to the building 300 by identifying a parcel delivery in response to detecting movement (via the camera 208 and/or via the motion detector 218) within 30 seconds of detecting sounds indicative of a delivery vehicle.

In FIG. 5 illustrates a perspective view of the floor covering 235. The view of FIG. 5 shows a front view of the door 254. FIG. 5 is a view that a visitor 388 typically sees as she walks towards a door 254 of a home.

FIG. 6 illustrates a diagrammatic view of the floor covering 235. FIG. 6 illustrates a top view of the floor covering 235 and a front view of the doorbell 202. Electrical wires 304 electrically couple the doorbell 202 to the floor covering 235 to enable the doorbell 202 to provide electrical power to the floor covering 235 (or vice versa). The doorbell 202 can receive electrical power from the building 300 (shown in FIG. 5) and then can provide at least a portion of the electrical power to the floor covering 235 via the electrical wires 304 (e.g., while the doorbell 202 is mounted to a wall of the building 300 and while the floor covering 235 is located on the ground). The electrical wires 304 can also be used for one-way communication and/or two-way communication between the doorbell 202 and the floor covering 235.

Several embodiments do not include electrical wires 304 between the doorbell 202 and the floor covering. The doorbell 202 can send communications 230 c to the floor covering 235 wirelessly. The floor covering 235 can send communications 230 a to the doorbell 202 wirelessly.

The floor covering 235 can comprise a PCB, a speaker 488 b, a light 216 c, a battery 462 b, a camera 208 b, and a motion detector 218 b. The floor covering 235 can also include a communication system 504 b configured to enable communication between the floor covering 235 and the doorbell 202. The communication system 504 b can include a transceiver. The communication system 504 b can be a Bluetooth communication system, which can use Bluetooth Low Energy.

The sensor 239 can be configured to detect parcels on at least 60 percent of the top surface of the floor covering 235. This configuration can help minimize the occurrences of failing to detect a parcel that is located on the floor covering 235. The sensor 239 can be made of many individual pressure sensors, light sensors, package sensors, and/or any sensor configured to detect a parcel.

Although some embodiments are described in the context of devices and systems, the device embodiments and the system embodiments can also be formulated as methods. Some embodiments include methods of detecting parcels. Methods can include obtaining a delivery parcel detection system comprising a doorbell having a first wireless communication system; and a floor covering configured for placement on an entryway floor. The floor covering can comprise a sensor. Methods can include detecting, by the sensor of the floor covering, a first indication of a delivery parcel on the floor covering. Methods can include communicatively coupling the doorbell to the floor covering; mounting the doorbell to a building; and/or placing the floor covering in on an entryway floor.

Several embodiments include sending a first communication from the floor covering to the doorbell in response to the floor covering detecting the first indication of the delivery parcel. Some methods include sending a second communication from the doorbell to a remote computing device in response to the doorbell receiving the first communication.

The second communication can comprise a first picture taken by the doorbell. Some methods comprise sending, by the doorbell, the first picture to the remote computing device in response to the floor covering detecting the first indication of the delivery parcel.

Referring now to FIGS. 7 and 8, in several embodiments, a delivery parcel detection system 700 includes a doorbell 702, a remote computing device 704, and a delivery parcel 706. The doorbell 702 may have a first wireless communication system 708 and a radio-frequency identification reader 710. The doorbell 702 can be attached to the outside wall of a building 711, for example near a door 713. The remote computing device 704 may be communicatively coupled with the doorbell 702 via the first wireless communication system 708. The first wireless communication system 708 may be configured to interface with or include a wireless network 709. The delivery parcel 706 may have a radio-frequency identification tag 712. When a parcel 706 with a radio frequency identification tag 712 is left near the door 713 by, for example, a mail carrier, the doorbell 702 can detect the parcel 706. The doorbell 702 detects the parcel 706 by the radio-frequency identification reader 710 reading the radio-frequency identification tag 712 of the delivery parcel 706.

When the doorbell 702 detects the radio-frequency identification tag 712, a first communication 714 can be sent from the doorbell 702 to a remote computer system 716. The remote computer system 716 may comprise a database 718. The remote computer system 716 may be affiliated with the sender. The database 718 may have information 715 regarding the delivery parcel 706. A second communication 720 may be sent from the remote computer system 716 to the doorbell 702 in response to the remote computer system 716 receiving the first communication 714. The second communication 720 may comprise the information 715 regarding the delivery parcel 706.

In some embodiments, the system 700 may further comprise a third communication 722 sent from the doorbell 702 to the remote computing device 704 in response to the doorbell 702 receiving the second communication 720. The third communication 722 can contain the information 715 that was received by the doorbell 702 from the sender. The third communication 722 may also contain a time 724 indicative of when the doorbell 702 first detected the delivery parcel 706.

For example, the user may order a product from the sender online. The sender ships the product and when it arrives on the doorstep (the delivery parcel 706), the doorbell 702 detects the parcel 706 and sends a communication 714 to the sender that the parcel 706 has arrived at its destination. The sender may then send information 715 associated with the delivery parcel 706 back to the doorbell 702. Once the doorbell 702 has this information 715 it may send it on, in another communication, to the user, thus allowing the user to be notified that they have a parcel 706 and information 715 about it. The communication may also notify them of the time of delivery of the parcel 706. The information 715 associated with the delivery parcel 706 may be a description of the contents of the parcel 706, the name of the sender of the parcel 706, the value of the parcel 706, etc. The remote computer system 716 may be, for example, a server, a website, a computer, or a workstation.

Referring now to FIG. 9, the doorbell 702 may also include a camera 730 to allow the user to see the parcel 706 that has been delivered. When the doorbell 702 detects a parcel 706, it may take a picture of the parcel 706 and send it to the remote computing device 704 in a fourth communication 726. A fourth communication 726 may also be sent from the doorbell 702 to the remote computing device 704 in response to the doorbell 702 receiving the second communication 720. The fourth communication 726 may comprise a first picture 728 taken by a camera 730. The first picture 728 may show the delivery parcel 706.

Referring now to FIG. 10, in several embodiments the system 800 may comprise a first notification 814 sent from the doorbell 802 to the remote computing device 804 in response to the doorbell 802 detecting the radio-frequency identification tag 812 of the delivery parcel 806. The first notification 814 may comprise a first picture 828 taken by a camera 830 of the doorbell 802 in response to the doorbell 802 detecting the radio-frequency identification tag 812 of the delivery parcel 806. The remote computing device 804 may have a display screen 832 to allow a user to, for example, view at least a portion of the first picture 828 displayed on the display screen 832. The system 800 may be configured to enable a user of the remote computing device 804 to see the delivery parcel 806 on the display screen 832 in response to the first notification 814.

Referring now to FIGS. 11 and 12, the doorbell 802 may be attached to a building 811, for example, near a door 813. The doorbell has a radio-frequency identification reader 810, which has a specific detection range 834. When a package is brought into this detection range 834, the radio-frequency identification reader 810 is able to read the radio-frequency identification tag 812 on the parcel 806. The system 800 may send a notification 814 to the remote computing device when a parcel 806 with a radio-frequency identification tag 812 enters the detection range 834. Likewise, if a parcel 806 with a radio-frequency identification tag 812 is removed from the detection range 834 (i.e. is no longer detected by the doorbell 802), the doorbell 802 may send a notification 820 to the remote computing device 804. The removal of a parcel 806 may trigger the camera 830 to take a picture 836. The picture 836 may allow a user to determine if the parcel 806 was stolen, or blown away, etc. The notification 820 that the parcel 806 has been removed could also alert a user when a parcel 806 is picked up by, for example, a mail carrier. The notification 820 that the parcel 806 has been removed may contain the picture 836 taken by the camera 830 of the doorbell 802 as well as other information (i.e. the time, date, etc.).

Referring now to FIGS. 13 and 14, the doorbell 802 may also detect when the parcel 806 is moving. It may detect the parcel moving by comparing strengths of two different signals 838, 842 from the radio-frequency identification tag 812 on the parcel 806. For example, the system 800 may further comprise a first signal 838 of the radio-frequency identification tag 812 detected by the doorbell 802 at a first time, a second signal 842 of the radio-frequency identification tag 812 detected by the doorbell 802 at a second time 844, and a second notification 820 sent from the doorbell 802 to the remote computing device 804. The system may determine that the parcel is moving farther from the doorbell 802 or is being removed if the second signal 842 is weaker than the first signal 838. In response to the doorbell 802 detecting the parcel moving farther from the doorbell or a removal of the delivery parcel 806 the doorbell 802 may send a second notification 820 to the remote computing device 804. The doorbell 802 may also take a picture 836 with the camera 830 in response to the doorbell 802 detecting the parcel 806 is moving or is removed. The second notification 820 may comprise the second picture 836 taken by a camera 830 of the doorbell 802. The radio-frequency identification tag 812 may be an active tag. The doorbell 802 may be configured to detect the delivery parcel 806 by the radio-frequency identification reader 810 reading the passive radio-frequency identification tag 812 of the delivery parcel 806. The doorbell 802 may be configured to detect the delivery parcel 806 by the radio-frequency identification reader 810 reading the active radio-frequency identification tag 812 of the delivery parcel 806.
